Phillips will start Sunday's series finale against the Guardians, Christina De Nicola of MLB.com reports.
Phillips last pitched Wednesday against the Mariners, but the Marlins are expected to heavily rely on their bullpen for Sunday's contest, so the veteran right-hander will take the hill on three days' rest and presumably operate with a limited pitch count. Phillips has recorded a 3.28 ERA, 1.36 WHIP and 55:34 K:BB across 74 innings this season.
